Are there any marine performance (for wood, plastic, ,metalls) glues that (compared to epoxi) are more... a) elastic? b) low density? c) as epoxi but 1 komponent? d) how is epoxi lowest density achived ? Morgan O. I rely on three main adhesive/sealants Epoxy(with various fillers) 3M5200(CALLED A SEALANT BUT HAS GREAT ADHESIVE QUALITIES) and a product called MArine GOOP (this stuff looks like that worthless silicon rubber product, but is nearly as strong as 3M5200 but more elastic) As for adhesision to various materials, if the adhesive is recommended for that material then the limiting factor becomes surface preparation. Bad or no preparation and ANY substance will fail. Which epoxy fillers do yo like the most? Morgan O. For 'glueing' I generally use a microfiber (like Wests' or similer), for filling/fairing either silica or microfiber or in some cases the two mixed 50/50. Silica HAS LESS STRENGTH BUT SANDS EASIER THAN THE MICROFIBER(damn cap key) I do not like the micro balloon as it leaks and is very permeable, but it sands really really easygrin Has any of you tried filling epoxy with the ~4-5mm EPS balls? It's not strong compared to GRP but it must be many times stronger then a 70Kg/m3 foam. Morgan O. |
